Wearable electronics are increasingly filling the shelves of technology stores. Not so long ago, ordinary people could observe the emergence of such a gadget as a portable speaker. With its help, you can create a simplified analogue of a music center, absolutely not tied to an outlet or a specific place. Controlling the device is quite simple, but not everyone knows how and how much to charge a portable speaker.
In this article, we will look step by step at methods for replenishing the battery of a portable speaker, as well as the reasons for the lack of charge.
Making portable charging
How to charge a phone if you have batteries, a compartment for them, a charger for them or an old mobile phone and a USB extension cord?
Batteries must be AA type. In addition, a soldering iron and tester should be available.
We take 4 batteries (preferably large capacity) and insert them into the battery compartment. We measure the voltage with a tester, it should be at least 5 volts. This is due to the fact that modern phones can be charged from a USB connector, in which the voltage is 5 V.
From a USB extension cable that you don’t mind using, cut off the plug that connects to the computer. We study the pinout of the contacts, call the tester. We find + and -, remove the remaining wires with wire cutters and insulate them.
We put a thermal casing on the wires and treat it with a lighter to ensure a tight entry. We try on the place where the plug is attached.
We will need to solder the wires to the metal rivets. For this purpose, soldering acid is used, which can be applied with a tin stick, after which we tin the rivets.
We solder the wires according to their charge.
The connector must be glued to the body, having first degreased or scraped off the connector and plastic with a knife.
Apply heated glue to the body and press. Apply glue around it, closing the open contacts. The remaining unnecessary wires are bitten off and covered with glue. If necessary, it can be masked using a marker.
We insert the batteries. They must be of the same capacity. Moreover, their total capacity must exceed that of a telephone battery.
How to understand that the device is charged
Modern music gadgets are equipped with a battery charge indicator, which displays the process of power supply to the battery. In its normal state it is not lit and should not blink. When the battery is full, the indicator will turn green. If there is little charge left on the JBL Jibiel Bluetooth speaker, the indicator will light up red. Charging it is easy: you need to connect it to a desktop computer and wait until the red color changes to green.
If the gadget does not have an indicator, then it is more difficult to understand that the battery is full. To do this, you need to remember the start time of the charge and count 3-4 hours. As a rule, this time is enough for another 5 hours of continuous listening to loud music.
Interestingly, the station also charges your phone perfectly. To do this, you need to set the switch to PS and connect both devices with a cable. As soon as the phone starts charging, the corresponding icon will appear on it.
In general, charging a device such as a portable jbl speaker is not difficult and can be done in just a few hours, while continuing to enjoy your favorite music from the speaker at home or outdoors in the pool.

This circumstance opens up new opportunities for fun leisure activities outside the zone of access to the power grid. The battery life of the average smartphone is short, and the music plays continuously - the device will be discharged about four hours after being fully charged. But a mobile speaker with a Powerbank function - such as Defender Moon Power - will save the situation. This small gadget is equipped with its own powerful battery with a capacity of 3000 mAh, so it will provide itself with power and also share it with your mobile device!
However, things are also not bad with sound reproduction. The Defender Moon Power mobile speaker uses a 2-inch speaker with a power of 2 W. It reproduces sound in the classic frequency range from 90 to 20,000 Hz and easily copes with music of any genre, as well as soundtracks for films and video games.
There are two ways to connect a mobile speaker to smartphones, tablets and any other signal sources. The most convenient, perhaps, is wireless - it is suitable for all gadgets that support data transfer via Bluetooth (and today, try to find a smartphone, tablet or player without this module). The connection is quick enough and does not require any special knowledge or skills.
If for some reason you don’t want to communicate with Bluetooth (well, for example, you have several wireless devices running at the same time and you are afraid of interference), then the speaker can be connected with a regular audio cable via the AUX connector. The cable is included with Defender Moon Power; there is no need to buy anything additional.
The mobile speaker is equipped not only with a speaker, but also with a microphone, so it can be used as a headset for a smartphone. In a word, we have a very functional device that will be useful at home, in the office, on a business trip, and even on vacation.
Defender Moon Power is made in the shape of a crescent (apparently, hence the name of the model). You can choose a device in a black or white case - to suit your taste. If we look at the gadget more closely, we will find several connectors and controls on its edges. Using the wheel you can adjust the volume, switch music tracks or receive an incoming call. One of the connectors on the body of the mobile speaker is designed for connecting smartphones or tablets to it in order to recharge them (the same Powerbank function mentioned above).
The Defender Moon Power battery, of course, also needs to be recharged from time to time. This can be done from any computer via a USB port, and the corresponding cable is also included in the kit. It is difficult to predict how long the charge in the speaker’s battery will last, but it will definitely be enough to give yourself and your friends many hours of fiery dancing. Or maybe it’s better to have a movie show and watch the whole season of your favorite TV series? Recharge with Defender Moon Power, a good mood is yours!

Common JBL problems
Despite their reliability, jbl portable speakers sometimes break down. As a rule, this is due to incorrect conditions of use, but sometimes a factory defect is found in the column. The solution in 65 percent of cases will be to contact a specialized service to repair and diagnose problems with the operation of the column. Going to a specialist is not always economically feasible.
We will describe in more detail possible problems with a bluetooth speaker and explain how in some situations you can repair the device yourself.
Interrupts
Frequent problems are interruptions in the sound from the speaker at fixed intervals or stuttering. In 40 percent of cases, the problem lies in an unstable Bluetooth connection between the player and JBL. Reconnect devices or connect via wire. If the stuttering does not stop, rule out an error in the music source, for example, a telephone, and replace it.
In 30 percent of cases, the problem of stuttering lies in the incorrect operation of the JBL frequencies. To correct this option, turn on the low frequency mode - press and hold the “Bluetooth” and “Volume -” buttons for 7-10 seconds. This action will help improve the sound. If interrupts are saved, the error lies in the JBL device. Then you can’t do without a trip to the repair department.
Not charging
Another JBL malfunction is that the device stops charging. Inspect your gadgets. As a rule, the violation is detected visually by paying attention to the micro USB connector. If it is damaged, the speaker will have to be disassembled and the charging connector replaced.
Why is the speaker not charging?
The reasons why the Jbl speaker does not charge may be the following:
- breakdown of the USB port or special charging socket on the speaker itself;
- failure of the charger;
- internal break or damage to the USB connectors of the connecting cable;
- a break in the battery circuit, or exceeding its service life;
- failure of the USB type A socket on a personal computer or laptop;
- There is no 220 V AC voltage in the socket to which the adapter is connected.
What to do if the socket breaks
The user can repair the charging port himself; he will need a set of screwdrivers, a soldering iron with tin and rosin, as well as minimal equipment repair skills.
As an example, we consider the repair of Jbl Charge 3, which is carried out in the following order:
- A thin blade is inserted into the slot on the bottom and the panel with the logo is unfastened.
- Do the same with the rear panel, after which the upper casing can be easily removed.
- Unscrew 8 screws located in the sockets on the panel with the Jbl Charge speakers.
- Carefully peel off the rubber base on the bottom and unscrew the 4 screws hidden under it.
- After removing the unscrewed base, the body easily breaks into two halves.
- For safety, the battery is disconnected from the main board.
- And also, before removing the central board from the grooves, the speakers and the Jbl Charge control panel are disconnected from it.
- If you have a multimeter, then the charging socket can be checked for functionality by connecting the connector of a working adapter to it. If, when connecting one of the probes to the body and the second to any of the connector legs, the device does not indicate the presence of voltage, then the socket needs to be changed.
- The non-working connector is unsoldered and replaced with a purchased new one.
- Assemble the Jbl Charge in the reverse order.
- Glue a rubber lining to the bottom.
How to extend battery life and service life?
The most common questions concern the features and rules for using a stand-alone mobile device. So, how can we extend the life of any battery, regardless of the type of battery used (Li-Ion, Li-Po, NiMH, NiCD)?
1. Temperature - Keep the battery cool and away from the sun and heating elements to reduce internal corrosion (parasitic reactions on the electrolyte and electrodes).
2. Deep discharge - remember that partial discharge is safe, but full discharge wears out the battery, it is optimal to keep the charge level from 30% to 80% (what is deep discharge).
3. Intensive work - choose phones that have a sufficiently powerful battery if you want to use your mobile device for games (like Pokemon Go) or resource-intensive tasks.
Apps that are dangerously draining your phone's battery life
4. Fast charging - use only original chargers when your phone supports one of the proprietary technologies (Qualcomm Quick Charge, Pump Express, VOOC, Super mCharge and others). But if you want to extend the battery life, then in everyday use with high power adapters, try not to exceed the charge level of 80%.
5. Battery storage - the worst factors are elevated temperature and high voltage, so it is optimal to place the phone or other gadget with a Li-Ion battery in a cool place partially charged (for example, up to 50%).
Charging rules
Before charging the battery for the first time, you must wait until it is completely discharged. Please read the attached operating instructions. The charging process lasts approximately 4 hours . The time may be slightly increased or decreased depending on different models.
The more common inexpensive speakers, in addition to the device itself, include a USB cable for charging it. Therefore, when choosing such a model, you will need to additionally purchase a power supply with a resistance suitable for a particular type of device. Typically, information about the current required to recharge a gadget is indicated on its packaging.
But if the speaker owner has a smartphone or tablet at his disposal, purchasing a separate power supply can be avoided. In most cases, the phone block is also suitable for a wireless speaker.
The set of Bluetooth speakers from well-known American and European manufacturers, which are expensive, already includes a power supply. There is no need to purchase it separately.
Despite different prices or manufacturers, all mini-speakers can be charged in two ways.
From the outlet
To charge the speaker from an outlet, you will need a cord and a power supply. To begin the process, you need to complete a number of steps.
- Turn off the speaker.
- Find a socket with a micro-USB connector on its body. It is located on the back of the device and is most often hidden under a silicone plug.
- Remove the plug by picking it up with a fingernail or a thin, but not sharp, object.
- Insert one end of the wire with a micro connector into the socket on the speaker body. And insert the other end with a standard USB connector into the power supply.
- Connect the power supply to the electrical network.
- Wait until the battery is fully charged.
- Unplug the unit from the outlet.
- Remove the wire from the speaker socket. Close the silicone plug.
You can use the device immediately after the charging process is complete.
From another device
There are situations when there is no outlet or power supply at hand. In this case, you can replenish the battery charge from a running computer, laptop or external power source. This requires a USB cable and a clear sequence of actions.
- Turn off the mini speaker.
- Turn on your laptop or computer.
- Connect these devices with a USB cable. Connect the micro connector to the speaker, and the standard connector to the computer.
- Wait until charging finishes.
- Sequentially disconnect the wire, first from the computer, then from the speaker.
You can use the speaker with this charging method immediately after disconnecting it from the power source.
You can charge the speaker directly from an external battery without even turning it off.
This method is very convenient on the road, traveling, transport, or when the battery level is low and playback cannot be interrupted.
How to troubleshoot connection problems?
To make the purchased speaker work, determine why it is not working and fix the problem.
Before the beginning
If you connect a portable speaker and it doesn't work, don't panic. Check the battery charge and see if it is turned on or not. It is worth paying attention to Bluetooth; if it is not turned on, the device will not be able to play sound. In 90 percent of cases, the startup sequence is described in the instructions that come with the purchased device.
Column not included
To turn on the column, click on “On”. But there are cases when when you press this button, the indicator lights do not respond. This indicates that the device did not turn on. The reasons are usually simple:
- The battery is 100 percent discharged;
- The device is faulty and requires repair.
Why is the speaker not visible via Bluetooth?
There are many reasons why the column is not visible when turned on. If you are not sure that you can fix the problems yourself, contact the service center.
In 80 percent of cases, the main reason is turned off Bluetooth. This happens in case of inattention or the visibility period of the paired device has expired. Before turning on, check if Bluetooth is turned on.
Drivers
The problem in 50 percent of cases also occurs in the computer. If the necessary drivers are not installed, the device will not detect portable speakers.
In addition, drivers may be incompatible with a modern device or computer operating system.
Pairing
When you buy a wireless speaker, most often it is connected to all the devices you have. This includes a computer, a tablet, a smartphone and even a TV. If you use the device with different devices, you will select the “Automatic connection” functions. In this case, other devices may not see the speaker because it is already connected to another device.
